Flexible Object Models for Category-Level 3D Object Recognition
Today's category-level object recognition systems largely focus on fronto-parallel views of objects with characteristic texture patterns. To overcome these limitations, we pr...

Simultaneous Covariance Driven Correspondence (CDC) and Transformation Estimation in the Expectation Maximization Framework
This paper proposes a new registration algorithm, Covariance Driven Correspondences (CDC), that depends fundamentally on the estimation of uncertainty in point correspondences. Th...

The Hyperbolic Geometry of Illumination-Induced Chromaticity Changes
The non-negativity of color signals implies that they span a conical space with a hyperbolic geometry. We use perspective projections to separate intensity from chromaticity, and ...

Efficient Sampling of Disparity Space for Fast And Accurate Matching
A simple stereo matching algorithm is proposed that visits only a small fraction of disparity space in order to find a semi-dense disparity map. It works by growing from a small s...

Automatic texture mapping on real 3D model
We propose a full automatic technique to project virtual texture on a real textureless 3D object. Our sytem is composed of cameras and projector and are used to determine the pose...
